COMBINED HARROW AND ROLLER.

SPECIFICATION forming part of Letters Patent No. 395,366, dated January 1, 1889.

Application filed April 28, 1888. Serial No. 272,201. (No model.)

.To LZZ whom in' may concern.-

Be it known that I, JOHN T. VAN POOL, a citizen of the United States, residing at Tiptonville, in the county of Lake and State of Tennessee, have invented certain new and useful Improvements in a Combined Harrow and Roller, otf which the following is a specitication.

This invention relates to a combined harrow and roller; and its object is to provide a simple and improved device ot this character possessing advantages-in point of simplicity, inexpensiveness, dural'iility, and general etliciency.

In the drzuvings, lignre 'l is a perspective view of a combined harrow and roller embodying my invention. .lfigz 2 is a bottom or inverted plan view. YFig. 3 a vertical longitudinal sectional view. Fig. 4 a vertical transverse sectional view on. the lin e ir :12,Fig. 3. Fig. is a vertical transverse sectional view on the lille y y, Fig. Fig. (i is a detail jgierspeetive view ot' one oi the harrow-teeth.

Correspondingy parts in the figures are denoted by the same letters ot' reference.

Referring to the drawings, A designates a roller, which is journaled in bearings in the downward'ly-extending arms o o otl a crossbeam, B, having a seat, mounted thereon for the o perator.

D designates a rod or bar having its end port-ions, d d, bent at right angles to the main port-ion and provided with bearing-blocks d d', engaging the ends of the axes oi.' the roller. Proj ecting at right angles to the main portion oi the bar I) is an arm, E, provided with a series of perforations, c, towhich is bolted at the desired angle the perforated lower end ot' a lever, F.

G designates the htn'row, comprising, .preferably, an approximately U -shaped fram e, H, having bearing-plates 7L bolted to the ends thereof and engaging the bar D, and transverse bars or beams I, bolted or otherwise secured at their ends to the frame II, carrying the harrow-teeth. formed by right-angular plates, one portion of which is beveled, forming the teeth proper, while the other portion is provided with an eye, through which they are bolted to the transverse bars or beams I, and are so disposed thereon that eaeh tooth will be in a dif-4 These teeth are preferably ferent longitudinal plane. The teeth maybe formed by a plate having both ends bent at right angles to the central portion, thus providing a double tooth, as shown. at S, Fig. 2.

A rod or bar, J, is bolted to the bars or beams I at right angles thereto, and terminates at its front end in an upwardly-projecting segmental arm, J', provided with a series of eyes or perforations,j", through one of the lower ones of which a clevis, K, is bolted. A doubletree, L, may be connected to the clevis, having' singletrees Ii L at its ends.

A tong'ue, lll, is provided,having fflivergent rods or arms MM provided at its rear ends, the free ends oi' said rods or arms being bent at right angles to the tongue, and are located in bearing-plates fm m, secured to one of the beams l. A vertical slot, m, 'is provided through the rear end ot' the tongue, through which projects the segmentalA arm J". The free upward play of the tongue in its bearings is regulated by a4 pin, je, engaging one ot' the upper eyes or perforatiom,j', above the tongue.

N designates a rod or bar connected at its rear liiifureated end, a, with a vertical plate, O, secured to the beam B by a bolt passing through said end and through one of a series of eyes or perforations, o, in said plate. The

front end of the rod or bar N is hook-shaped and removably engages an elongated slot, p, in a projection, P, on the rod or bar J'.

The operation and advantages ot` my invention will be readily understood by those skilled in the art to which it appertains. By operating the lever the harrow can be raised, throwing the weight of the same upon the roller tor the purpose of freeing' the harrow from all obstruction, while the relation. of the harrow to the ground can be regulated bythe adjustment ot.' the clevis, tongue, and rod or bar N.

It will be obvious that the harrow may be used exclusive of the roller by removing the bolts securing the bearing-plates 71 and releasing the rod or bar N from engagementv with the slot in. the proj ection l?.

I claim as my inventionl. In a combined harrowand. roller, the combination, with the frame j orovided with an arm proj eoting therefrom, of a leveradj ustably secured to said arm, substantially as set forth,

The Combination, in a Combined lim-row and roller, with the roller, t horizontal traine having bearings :it its ends for the szu11e,alever for adjusting said freine, and at harrow Connected with the lutter, of n bemn connected with the roller-axes and provided. with n seat and an adjustable bar Connecting said bezun and harrow, substantially as set forth.

5. The herein-described harrow and roller,

consisting of the roller, e bezun Connected with the axes th ereo'f an d pro vided with a seat and an apertured plate, :L frame having beerings at its ends for said axes and provided with an adjusting-lever, L hznrow Connected with said frame and Carrying an adjustable tongue, fr Slotted lug on said barrow, and a bar adapted to adj ustably engage said lug and the said aperturedplute, substantially as set forth. In testimony whereof l aiix nl v signature in presence of' two witnesses.
